Abstract
A monitoring device/module monitors a plurality of nodes in a data center network, and determines one or more latency distributions of response times for messages exchanged between pairs of nodes of the plurality of nodes. The network monitoring device determines a network topology, including one or more communication links interconnecting nodes of the plurality of nodes, consistent with the one or more latency distributions. The network monitoring device also determines a representative response time for each communication link based on the one or more latency distributions, and compares a current response time a message exchanged between one pair of nodes to the representative response time for the communication link interconnecting the one pair of nodes. The network monitoring device identifies a network anomaly when the current response time deviates from the representative response time for the communication link interconnecting the one pair of nodes by a threshold amount.
